What are dental crowns?

Dental crowns are used to fully cover a damaged tooth. Aside from strengthening a damaged tooth, they can also be utilized to enhance the tooth’s alignment, shape, and appearance. They can be put on top of a dental implant in order to provide a tooth-like structure and form for better function.

What are dental crowns made of?

Dental crowns can be made of a broad range of diverse materials. A few of the most renowned ones include the following:

All-ceramic

This is regarded as a contemporary method that offers a metal-free option. It can provide the strength of a bonded crown and appears like that of a porcelain crown. Hence, it is appropriate for use in many areas of the mouth.

Porcelain bonded to metals

These types of a dental crown are a combination of metal and porcelain crowns. When the dental technician makes them, they first form a shell of metal that accurately fits over the tooth. Afterward, a veneering of porcelain is combined with this metal. As a result, the crown obtains a pearly tooth-like look.

Advantages

These types of dental crowns are ideal for both back and front teeth primarily because they are very durable and come with an appealing look.

Disadvantages

These can form wear on the teeth it bites on or rubs against. They can break or chip at times. They often show the metal right at the edge of the crown. So, if you are suffering from gum recession, that metal may be revealed and destroy the entire appealing look of the crown itself.

Porcelain

These are manufactured fully out of porcelain; however, they are not as durable as bonded crowns. The good thing about them is that they look like a natural tooth and are used more frequently for front teeth.

Advantages

These are an ideal option for restoring front teeth since they are commercially pleasing.

Disadvantages

These are not as durable as porcelain-fused-to-metal or metal dental crowns. Due to this, they may not be an ideal alternative for back teeth.

All-metal or gold

In reality, gold is considered one of the oldest filling materials. At present, it is utilized with other metal alloys to enhance its strength, which makes it quite serviceable. Typically, they are silver or gold in color.

These are typically manufactured of a gold alloy. But, many different alloys can also be utilized for making dental crowns. A few of these metals come in a silver color instead of a gold-like hue.

Advantages

These are specially crafted using malleable materials. So, it is a lot easier for the dentist to obtain a very accurate crown-to-tooth fit.

These types of dental crowns do not wear excessively on the teeth that oppose them. They are very sturdy. In fact, they can deal with hard chewing and bite.

Glass

These dental crowns can be used in all areas of the mouth, and they appear very natural.

Why do I need a dental crown procedure?

Dentists may recommend a crown in response to various dental needs. A few of these reasons include:

  • To encase a tooth that underwent a root canal treatment

  • To cover a stained or poorly formed tooth
  • For the restoration of a broken tooth
  • To strengthen a weak tooth as a cause of decay or to hold a cracked tooth together to prevent it from breaking entirely
  • To support a bridge
  • To replace or cover a large filling when there is not enough tooth left

How is the dental crown procedure done?

Crown Preparation

First, the dentist will give the patient a local anesthetic. He or she will afterward file down the tooth that requires being fixed. The dentist will prepare the tooth to the right shape for the crown. This composes of clearing away a layer of the outer surface and at the same time leaving a strong inner core. Take note that the amount of tooth extracted will be the same as the crowns thickness.

By the time the tooth is shaped, then the dentist will take a mold or impression of the prepared tooth. This is done on one of the opposing jaws and perhaps another to demonstrate the manner you bite together.

Afterward, the mold or impression will be handed to a dental technician, along with the vital information needed and other data regarding what shade to use.

Temporary Crown

Next, the dentist will put a temporary crown on the tooth that requires being fixed till the final crown is prepared. Be reminded that the temporary crown is created from an impression of the patient’s tooth prior it was filed down.

This shields the tooth until the final crown is prepared. It is essential to know that the temporary crown may not have the same color as well as the shape of the final crown.

Final Crown

Then, the dentist will pull out the temporary crown and will securely place the final crown on your next dental appointment. He or she will thoroughly check to ensure that the crown comes with the right bite, color, shape, and fit. If it perfectly fits you, he or she will cement the crown into place.

Who does a dental crown procedure?

This is a dentist who has fully completed a university post-graduate expertise in the field of prosthodontics. A specialty in dentistry which deals with replacing and restoring tissues and natural teeth with the use and help of artificial substitutes are called prosthodontics.

Which type of dental crown should I get?

Typically, it is a bit hard to recommend what form of dental crown suits the patient best. This is because the decision must rely on the patient’s budget as well as the form of a dental issue he or she has.

All-porcelain dental crowns have very outstanding cosmetic appeal; however, these are overpriced and are less durable. Moreover, they may only be a good choice for patients who wish to restore their front teeth.

On the other hand, zirconia and porcelain-fused-to-metal crowns are ideal alternatives in restoring the molars.

How long does a dental crown procedure last?

A minimum of two dental appointments is needed. At the initial visit, the dentist will need to prepare the tooth, take the impressions, record the information and shade of the patient’s tooth, and then fit the temporary crown. The next visit will be the time for the dentist to fit the permanent crown. Please be guided that there will typically be about one to two weeks between appointments.

How much is a dental crown procedure?

In truth, costs shall vary depending on the material used and the type of crown you prefer. It is advised to get a written estimate and treatment plan first before starting any dental procedure or treatment, so you can prepare for the cost beforehand.

How long do dental crowns last?

How long your crown lasts depends on how well you take care of it. Crowns can actually last for several years provided that you take proper care of them. Your dentist can tell you how long your cap may be expected to last.

How can I maintain my dental crowns?

It is vital to keep the crown clean just like your natural teeth. While it is true that the cap itself won’t decay, still, the decay can emerge where the edge of the crown links to the tooth. Brush at least twice a day using fluoride-based toothpaste, floss regularly, and rinse with a fluoride-containing mouthwash. These habits will help avert periodontal problems and tooth decay. Maintaining a well-balanced diet with restriction to hard foods is also recommended.

Mannerisms such as finger-biting and teeth-grinding should also be avoided as these considerably accelerate crown wear-and-tear. If teeth-grinding or clenching is an unpreventable habit, the dentist may recommend the usage of a mouth guard during night time.
